' SINK POSITIONING MECHANISM Filed Dec. 4, 1950 2 Sheets-Sheet 2Patented June 21, 1932 PATENT OFFICZE EDWARD N. CAVERT, OF CHICAGO,ILLINOIS, ASSIGNOR OF ONE-THIRD T SAMUEL PETERSEN AND ONE-THIRD '10GEORGE B. ARCHER, BOTH OF CHICAGO, ILLINOIS SINK POSITIONING MECHANISMApplication filed December 4, 1930. Serial No. 499,920.

This invention relates tosink positioning mechanism, and moreparticularly to manually operable means for quickly and convenientlychanging the relative height of a kitchen sink or the like. A moreparticular object of the invention is to provide means by which theelevation of a sink may be changed to suit the height or convenience ofthe person using the sink at the particular time. It is impossible topermanently install a kitchen sink that will be of a height to suit allindividuals, and as a result a great deal of fatigue and tedium occurwhen a housewife or servant is compelled to use a sink that ispositioned either too high or toolow. It is to overcome this problem andprovide simple yet practical and durable means for enabling the sink tobe raisedor lowered to any desired level to suit any particularindividual, that the present invention is directed. It will beunderstood that this is of especial advantage in apartment buildingswhere a change in occupants of an apartment occurs frequently.

Other objects will appear hereinafter.

This invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings forming a part of this specification, and in which:

Fig. l is a plan view of a typical kitchen sink, with the mechanism ofthe present invention applied, taken substantially on the line 11 ofFig. 3;

Fig. 2 is a vertical sectional view taken substantially on the line 2-2of Fig. 1;

Fig. 3 is a vertical sectional view taken at right angles to Fig. 2centrally of the operating mechanism; and

Fig. 4 is a perspective view of the supporting frame, slidable block,and operating screw of the apparatus.

The preferred embodiment of the invention is shown in operativeassociation with a kitchen sink 6 provided with a drain pipe 7. Theseparts are adapted to be moved vertically to any desired position andrigidly maintained at such selected elevation, and the mechanism forproviding this operation pref} a erably comprises a supporting frame 8which may be secured in place within a wall by means of bolts or screws9 extending through opening '10 and secured to the vertical joists. Asshown, the supporting frame 8 includes a lower transverse brace 11 andan upper transverse brace 12. The upper brace member 12 may be providedwith openings 13 for receiving and supporting the water supply pipes 14connected to the faucet 15. Inasmuch as the pipes 14 and faucet 15 arestationary, the splasher portion of the sink 6 is preferably providedwith a vertical slot 16 for each pipe 14:, and to prevent this slotopening on the exterior surface, a spring plate 17 is preferably securedadjacent the base of the faucet 15 and is adapted to conform'to thesurface outline of the adjacent splasher portion of the sink in anyelevated position.

The means for raising and lowering the sink in the preferred embodimentcomprises a block member 18 which is formed with lateral channelportions 19 adapted to embrace the vertical portions of the frame 8 andthus serve to guide the block 18 and also maintain the same rigidly inany position. The sink 6 may be secured to the block 18 by means of aplurality of relatively heavy screws '20 which pass through the block18, as shown,

and are threaded into rearwardly extending bosses 21 integrally formedon-the rear wall of the sink. Vertical movement of the block andconnected sink at this point is permitted by reason of vertical slots 22in the wall surface 28 to accommodate'the screws or bolts 20. The block18 is provided centrally with a vertical internally threaded portion toengage the threaded portion 2a of vertically disposed operating screw 25which is journaled intermediate its length in opening 26 of brace 11,and at the lower extremity is provided with a reduced portion 27journaled in the bracket 28 suitably secured interiorly of the wall. Thelower extremity of the operating screw 25 carries a bevel pinion 29adapted to mesh with bevel pinion 3O securedto shaft 31 journaled inbracket 32. It will be noted that shaft 31 extends through the wall 23and has secured thereto a hand operating wheel 83 positioned adjacentthe wall surface.

In the preferred embodiment shown, the drain pipe 7 is adapted totelescope within the stationary drain pipe 3% which is connected to trap35 as in the usual construction. The upper extremity of the stationarypipe 34: is preferably threaded for engagement with the internal threadsof bushing nut 36, having a reduced upper annular portion 37 adapted toembrace the drain or outlet pipe 7 and to con fine the packing 38preferably provided to render the joint leakproof in any position. Asshown, the nut member 37 carries laterally extending arms 39 by means ofwhich the member may be manually tightened or loosened.

The operation of the device is largely indicated by the foregoingdescription. To selectively position the sink 6, it is but necessary toloosen the nut 36 which may be done by means of the arms or handles 89and then turn the positioning Wheel 33, to bring the sink to any desiredelevation. When the selected position has been reached, it is butnecessary to tighten the nut 36 to provide a leakproof joint through thedrain connection.

' While I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modification without departing from the spirit of theinvention. 1, therefore, do not wish to be limited to the precisedetails of construction set forth, but desire to avail myself of suchvariations and modifications as come within the scope of the appendedclaims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. Incombination, a sink, an outlet pipe for said sink, a stationarydrain pipe, means for providing a leakproof connection between saidoutlet pipe and said drain pipe at any selected elevation of said sink,a stationary supporting frame, a block member slidably mounted upon saidsupporting frame and connected to said sink, and a vertically extendingscrew member in threaded engagement with said block member for raisingor lowering said block member and sink to any selected position.

2. In combination, a sink, an outlet p1pe for said sink, a stationarydrain pipe, means for providing a leakproof connection between saidoutlet pipe and said drain pipe at any selected elevation of said sink,a stationary supporting frame, a block member slidably mounted upon saidsupporting frame and connected to said sink, a vertically extending crewmember in threaded engagement with said block member for raising orlowering said block member and sink to any selected position, andmanually operable means for rotating said screw member.

3. Sink positioning mechanism of the character described comprising, incombination, a sink mounted adjacent a wall surface, a supporting framerigidly mounted within the wall rearwardly of said wall surface, a blockmember slidably mounted for vertical movement upon'said supportingframe, a rigid connection between said sink and said block memberextending through a vertical opening in said wall, operating meansconnected to said block member for raising and lowering the same, andmanually operating means mounted exteriorly of said wall surface foractuating said operating means.

4. Sink positioning mechanism of the character described comprising, incombination, a sink mounted adjacent a wall surface, a supporting framerigidly mounted within the wall rearwardly of said .wall surface, ablock member slidably mounted for vertical movement upon said supportingframe, a rigid connection between said sink and said block memberextending through a Vertical opening in said wall, a verticallyextending screw member in threaded engagement with said lock member forraising .or lowering said block member and said sink to any selectedposition, and manually operable means mounted exteriorly of said wallsurface for actuating said screw member.

In testimony whereof I have signed my name to this specification.

EDWARD N. CAVERT.
